### Project 875 — Portfolio Systems Acquisition (PSA)

This program supports the Department's initiatives to Restoring Warrior Ethos, Rebuilding Military Capabilities and Re-establishing Deterrence, and the National Security Strategy, especially in the areas of capability advantage and military superiority. These efforts entail integrated roadmaps to support acquisition investment decisions, and assessments of MDAPs and other linchpin acquisition efforts in a capability area context. PSA funds provide support in the areas of (1) integrated acquisition portfolio analysis; (2) acquisition roadmaps; and (3) acquisition decision support. Focus areas include capability portfolio management of air, land, sea, and undersea warfare portfolios, programs, and associated munitions; munitions acceleration efforts in support of the Deputy Secretary-chaired Munitions Acceleration Council; and Acquisition Transformation activities, executing the Department’s Acquisition Transformation Strategy. These efforts guide the development and fielding of integrated acquisition systems in order to achieve Joint mission capabilities across the operational domain to defend against global threats.
